@Hamin I mean, none of those other skills require being a sadist at all. Being skilled at doggy probably would at least include the standard stuff too, though maybe also pegging.
Though, the fact that even golden shower gets it's own specialized category (kinda dumb) I think if she did much pegging she'd have a pegging skill too. It's not like doggy is inherently associated with pegging on it's own.
If anything removing dominate person is probably the most important, getting rid of sadist wouldn't hurt, and there you go.
